GARDEN-IMP EMENT.

To ALL WHOM fI'r MAY CONCERN} Be it known that I,'JAMns AgMsrnoNe, of Buc yrus, in the countyof Crawford, and State of flhioghave inyented a, new and useful implement for hand-use in. the garden, aPuI erizer .andtGultivator and Rt1k0.0Qm-

bined; and'I do. hereby declare. that the following is'a' fuIL clea'r, and" exactdescription .theredf, reference" I being had to the acccimpanying drawings, making-a part of this speei'ficaition 'in which- Fignre'lis a top view-of implement. Figure 2 is an end view of implement, Figure 3 is a back view of implement, when used as arake. Figure 4.is an end view of imp'lemenflwhen used as a. rake. Similar letters of reference indicate corresponding partsin the several figures, .This invention relates to certain novel and useful improvements for pulverizing the groun in'gvegetaliles. 'l i. To enable others skilled in the art to'make and u'se my invention, I will describe its construction and operation. I It-is constructed with two rollers O Q, with gudgeons or pivots in each end. 'The-rollersare heldjby iron frame B B, in horizontal position, so as to allow the'rollers to rerolye when the imnlement is. moved back I --forth in the ground, Teeth are set in r-ollers so as to extend out three or four inches. Rollers C C are held by frame B, so that the outer, pointscf the teethwill clear the corresponding roller. The: thickness of roll- .ers should not exceed two inches.- The space between the teeth, lengthwiseof thetrollers, 5 1 n 6x0ed two inches, and abmit'eight'teeth in each'eirele on circumference 'of each-roller. The handle a enters aneye in frame B, and is held bywedge cl, and when used as a ralre, the handle' a-is placed throughthe eye in frame 3,. so as to'lock the lower roller, by coming in'contact with-the teeth in lo'weri oller; thischange forms a rake. This implement, as a whole, is formed of two 'rollers', held by frame B, as herein described, mailed -by handle a. The teeth in the rollers pass each other in opposite directions, when the implement is in operation {in the ground, so that the ground, as it passes between the teeth, is crushed," and left loose and mellow. When" i used as a take, the teeth will strike the ground at any angle or elevation of the handle. What I claim as new in my invention, and; desire to sec'ure by Letters Patent, is

The sliding of the handle A through the eye of the frame 3. So as to lock the lewerxoller C, by coming in contact with, the teeth of said lower roller, in combination with all the-ether devices aforesaid, as herein described for the purposes set forth.
